Heat pumps are widely used in Orkney, both domestically and on a larger scale. Orkney’s mild climate lends itself to heat pumps being used in domestic settings and many units can be seen on the exteriors of dwellings and public buildings. Notable examples include ground source heat pumps at Kirkwall Grammar School, Stromness Primary school, Papdale Halls, and the new developments at the Pickaquoy Centre. Unusually, a seawater heat pump can also be found in Orkney Islands Council’s Warehouse Buildings in Stromness. Heat pumps are especially effective as a renewable energy technology in Orkney, as even the electricity they use to run is produced from a significant amount of renewable sources.
